Chickpeas (Garbanzo Bean) are 23 per cent protein, but aren't complete

Low in fat and yet high in protein, chick peas are a great addition to the diet. They are inexpensive, too, so make a nutritious low-cost alternativeto poultry and meat. Chick peas are 23 per cent protein, but aren't complete, so mix with another bean, some rice or, as in houmous, some sesame seeds.
